War-weary Sam Worthington

A 3-D science fiction epic written and directed by James Cameron, Avatar tells the story of a reluctant hero who embarks on a journey of redemption and discovery, ultimately leading a heroic battle to save a civilization. Starring Sam Worthington, Zoe Saldana, Stephen Lang, Michelle Rodriguez, Joel David Moore & Sigourney Weaver.

Sam Worthington gets tired of "running around with a gun while stuff's blowing up" in films.

The 35-year-old actor has taken action star roles in films including 'Terminator Salvation', 'Hart's War' and 'The Debt', but enjoys it when he gets to do other roles with a little more weight, such as his turn as the star of 'Macbeth'.

He said: "Sometimes it's refreshing to not have to run around with a gun while stuff's blowing up all the time. It reminded me of movies I did when I was in Australia a few years ago.

"A lot of roles I get offered are to run around, yell and smash s**t."

Sam also starred in science fiction epic 'Avatar' - about humans who come into contact with a group of blue alien creatures called the Na'vi - and added some of the roles he gets offered look a little familiar.

He said: "I got one that was actually set on another planet with a bunch of green cat-like people. I was looking at it going, 'Is this for f***ing real?' I literally looked at it and said, 'You've got to be joking."
